5 county of Pierce, in the State of Washington,

have invented a new and useful Yard-Truck, of which theA following is a clear and concise specification.

Miys invention relates primarily true in which a car provided with flanged 'wheels adapted to run on the track ladapt'- ed to swing the lumber piled thereon transversely of the said track, it is also provided with a. means lfor lowering the lumber so that said lumber will rest on horses vthus allowing the ca-r to be removed from its load.

My device is articularly useful in hanlumber an is ada ted to operate in lum er yards where trac s are layed out in :spurs or switches which may be used for temporarily storing the lumber.

- The object cfm invention is to provide ayard truck whic will expeditiously-load v'and unload lumber by swinging the lumber 5 piled' thereon transversely of the track on which the .said truck is adapted to run.

Another object is to provide a means for raising and lowering the platform of the said -Tyard truckwhich will deposit the lumber of pled thereon upon horses or the like and by rther lowering the 'said platform I afford a'inovel means of removing my device from 'itsload.

I accomplish these objects by the construction" illustrated in the accompanying draw-A in inwhioh '1- 'gure 1 is a side elevation of my device.

' Fig. 2 is a plan view ofmydevice showing the platform an'd raising means removed. 4'0

Fig. 3 is a fragmentary section of 'a modification showing the means for preventing 'the bearing ring from permittin the platform to 'tip because of an unbalance load. Fig. Y4 is a transverse section of my device showing the lowering crank removed. Fig. 5 is a fragmentary view of a modification of the sprocket-nut showing a means for preventing the said sprocket-nut from being raised from its bearing.

\ parts throughout the several views of the accompanying drawings. I have provided a frame 1 provided with I flanged wheels 2 adapted to run on rails of 55' the yard tracks, the said frame 1 is alsol proto yardl Similar reference numerals refer to similar4 tively in the center of the said frame and is sported by a decking .4 which also supportj'l t e earing 6 which supports the king The elevating frame work S is also provid with an underdecking 9 and the bea l vided with a bearing ring 3fdisposed1-relas."

lO as well as the bearing 11 adapted to t thel said king pin 7. The elevating frame 8 is also adapted to support the sprocket nuts 12 which raise and lower the screws 13 which' support the platform 15. I haveI shown'a chain 16 adapted to fitvthe said sprocket nuts 12 and a driving sprocket 17 .adapted to operate the several sprocket nuts 12 sin'iul. Y

taneouslyA I have also shown thebearings which support the shaft i8 which is rigidsecured to the said sprocket 17 as being adapted to adjust the tension ofthe chain 16', l. I do not Wish, however, to be limited to the specific construction shown but wish to depatent as it may be desirable to adjust the part from details within the scope of my idlers Ai9 which are stationary by the con-Y. struction illustrated in the accompanying drawings.

I, am aware that there are trucks provided with a means for elevating their decking. or y platform, but Wish to claim -as my invention the means for swinging the lat orm trans-'- versely of the frame 1 in com ination with'a car or truck with the construction illustrated in the accompanying drawings and heretofore set forth.

transfer the load thereon to'horses which are.

ool

placed on either side of the track. Thev platform 15 is then swung transversely of the track and the said platform 15 isr lowered permitting each end of the said pile of lum er to rest u. on the horses and on furtherl lowering' to a low my device to be removed therefrom. The platform is then raised and ioo the next load is p1led thereon and so on until the spur is entirely filled throughoutv its length with piles of lumber on said horses. I do not wish to be limited to this particular use as it may be desirable to run the track tov a point to where a e'ar or vessel is loading from the horses so that another load may be su plied from another part of the yar thus t 1e next load is in readiness to be deposited on the horses after thelumber has been transferred therefrom to the said; car'or vessel,

Having thus described my invention what I claim as new and' desire to secure by Letters Patent in the United States is:

` 1.v In a yard truck of the nature indicated, a truck or car havin a frame work 1 provided with anged w eels 2 the said frame Work 1 adapted to support a bearing ring 3 and the king-pin 7 by means of decking 4, an elevating frame 8 rovided with" an underdecking having a earing-ri 10 and a beari 11 adaptedl to t the saidl 'ngin 7 ,.the said elevating frame'8 being provi ed With raising and lowering. screws 13 adapted to supporta platform 15 all substantially as shown and for the urpose set forth.

2. In a yard truclg of the nature indicated,

- a trucker car having aframe work 1 provided with flanged wheels 2, the said frame Work 1 adapted to support a bearing ring 3 and the v king-pin 7 by means o1' decklng 4, an elevatframe 8 provided with an underdecking 10 anda bearing 11 adapted to fit the sai king-pin 7, the said elevating frame 8 being provided with raising and lowering'screws 13 ada ted to support a platform 15 all substantia ly as shown and for the purpose set forth, means for g car havin operating the raising and lowering screws 13 simultaneously by sprocket nuts 12, means for tightening theI chain traveling thereon and means for driving the said chain which is rigidlysecured to t e shaft 18. 3, In a lumber handling device, a truck or a frame wor 1 anged W eelsyfthe said rame work 1 adapted to supporta bearing ring 3 and the king-pin 7 by means of decking 4, an elevating frame 8 provided with an underdecking 9 aving a bearing-rin 10 and a bearing 11 adapted to 'tthe sai king-pin 7, the said elevatin vframe 8 being provided with raising and 'owering screws 13 adapted to sulpport a platform 15, means for operating t e rovided with raising and lowering screws 13 simuitaneouslybby s rocketlnuts, 1,2, means for tighteni the ciain trav lingjthereon and means forV riving the said?l chain which is rigidly secured to the shaft 18.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
